To all whom it may concern:

Be it known that I, EDWARD E. GOLD, a citizen of the United States,residing in the borough of Manhattan, city, county, and State of NewYork, have invented certain new and useful Improvements in Coupler-Locks, of which the following is a specification.

My invention relates to locks for rigidly and positively lockingtogether couplers used for coupling the ends Of steam hose for railwaycars.

Locks of various kinds have heretofore been devised and applied tocouplers for imposit-ively locking the said couplers together. Suchlocks were designed to yield and permit the couplers to uncouple uponthe happening of various contingencies. My lock is not designed,however, to permit the automatic uncoupling of the couplers. On thecontrary, it is intended to lock the couplers at all times and toprevent any accidental uncoupling.

My invention has for its object to produce a positive lock for couplers.

A further object is to produce a lock that will hold the couplersclosely together, notwithstanding wear on the gaskets and other parts,and that will compensate for such wear. l i

Other objects will appear as the desc-ription proceeds.

My invention consists in Ithe employment of one or more clamps which areillustrated as substantially Vshaped, and the arms of which divergetoward their free ends and which are mounted upon the couplers in suchmanner that the same may slide transversely, and that when driven eacharm of the clamp will slide behind a projection from the oppositelydisposed mating couplers and force the `couplers together, and hold themin suchposition.

Desirable forms in which my invention may be embodied are illustrated inthe accompanying drawing where,-

Figure 1 is a plan view partly in section of a pair of couplers,illustrating my invention as applied thereto. Fig. 2 is a side elevationsimilar to Fig. 1. Figs. 3 and t are views similar to Figs. 1 and 2,illustrating a modified form. Figs. 5 and 6 are also-.views similar toFigs. 1 and 2, illustrating a still further modified form. Fig. 7 is adetail elevation of the coupler ports and lugs.

.pler body Fig. 8 is a perspective View of a modified form of clamp.

I have illustrated my invent-ion as applied to couplers of the familiarGold directport type. In this construction each cou- A has a direct porta and an arm B. Upon each arm B is a flange o which interlocks with aprojection a from the side of the body i of the coupler. The couplersare assembled by a downward swinging movement which causes the flanges bto pass behind the projections o@ This results in forcing the ports atogether.

My' present invention relates to means whereby when said couplers are soforced together and held by the flanges Z9 and locking projections a',they may be positively locked inv such coupled position and preventedfrom separating by an upward pull upon the hose. According to myinvention I provide each coupler member with a lug C upon its upper facewhich is perforated at c, the perforation extending horizontally in adirecn tion transverse of the coupler. Within this perforated lug uponone member o-f the coupler is mounted an arm (Z of a clamp I). This armd is a trifle longer than the other arm cl of the said clamp, and thearm d is made longer for convenience of inserting the clamp, as it iseasier to insert one arm at a time.` The inner part of one arm of theclamp is preferably slightly roughened as at Z2 for engagement with thelug C so that the clamp maybe held in the posit-ion to which it may bedriven. Suit-able means may be provided for preventing loss of theclamp. As illustrated, such means comprise a chain E secured to theclamp at one end, and the opposite end of which is secured to a lug e inthe coupler, or other means-might be provided for maintaining the clampin position, as by enlarging the arm Z so that it does not pass out ofthe lug C.

In Figs. 3 and t a modified form is illustrated. I-Iere the clamps arelettered F and each has an enlarged head f and is mounted within a lugGupon the coupler. Upon the other coupler is situatedalug I-I whichreceives the arm f of the clamp F. This arrangement is duplicated uponeach coupler so that there are two clamps F, each of which islmaintained in position in the lug G and each o-f which may be driventransversely of the couplers into the perforated lug II. It will beperceived here that the free arm f clamp is driven.

y In Figs. 5 andv 6 a further modified form of locking device isillustrated. Here the lettered I are each mount- J, and each clamp isroughened at e' to retain its position when it is locked. Suitable meansare provided for holding the clamps which may comprise the enlargedheads z". are designed to inter- To facilitate such of the clamps arepreferably beveled slightly at their forand the inner meetmg edges arepreferably made flat or even Here the clamps are driven together asillustrated in Fig. 5, 2 passes within the opposite clamp and engagesthe rear side Thereby as said clamps are driven together the coupler isfirmly and rigidly locked in place.
